Regarding making NCAA teams & scholarships:
Because the signing season for NCAA scholarships starts is February, track athletes are judged primarily on their performances in grades 10-11 (and the summer after grade 11). Scholarship money for guys requires some pretty serious times (which I’m not familiar with for male hurdlers); ESTII could tell you what the range is for when some money starts being offered. USA can get very expensive if you aren’t getting mostly full-ride, though you could walk on to places assuming you show progression into next year. The decision about Canada vs. USA is a personal one that should be discussed with family. There is a pretty long thread on it on the can.milesplit.com forums you might want to read through. I have a graduating athlete staying in Canada next year despite getting full-ride offers from good schools.
One thing to note: the BC Team standard is 14.80 with the 110m 36" hurdles, which I think is within your capabilities if training goes well and you put together a good race.
